| Abstract: | The size and morphology of yttrium orthoferrite nanoparticles were examined in relation to the synthesis conditions. The chemical
composition of the crystalline phases resulted from heat treatment of the samples at 650°C varies with the procedure of coprecipitation
of yttrium and iron(III) hydroxides. At the same time, heat treatment at 750°C leads to formation of yttrium orthoferrite
solely. The size of the YFeO3 crystals is weakly dependent on the initial composition preparation procedure, and the size and shape of their agglomerates
are sensitive to the conditions of coprecipitation of the hydroxides. |
